Weir discloses Scope 1 and 2 emissions under GHG Protocol with third-party limited assurance and is on track for its 2030 targets. Core weaknesses: Scope 3 emissions (99.7% of footprint) have risen 113% since 2020 despite restatement; water data collection only began in 2024 with no aggregate reporting; and biodiversity impact remains unquantified despite identified dependencies in metals supply chains.
Weir Group scores 31/100 (Below expectations) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified August 2026.
That places Weir Group joint 588th of 847 companies scored, and joint 7th of 10 in Industrial Equipment / Machinery.

The 3 companies in the sector scoring nearest above Weir Group.
Spirax exceeds near-term emissions targets and holds third-party verified data across Scope 1+2, but Scope 3 supply chain reduction remains unproven.
See the breakdown →Xylem publishes comprehensive carbon and water data with SBTi-validated 2030 targets, but Scope 3 emissions rose 9% year-on-year while relying on economic intensity rather than absolute reduction.
